Abstract
Worker exposure to perchloroethylene (127184) (PCE) was determined at White Oak Drive-In Cleaners (SIC-7216) in San Carlos, California on July 25, 1978. The firm was included in an industry wide mortality and industrial hygiene study of dry cleaning workers exposed to PCE. The work force included a presser, a seamstress, a cashier, and dry cleaners and spotters. First aid supplies and a gas mask were available on the premises. Personal and area air samples were collected. Eight hour time weighted average (TWA) exposures to the dry cleaner and the seamstress were 17 and 6 parts per million (ppm), respectively. An area sample collected adjacent to the washer indicated an average PCE concentration of 5ppm. Samples collected in the dry cleaning area indicated PCE concentrations of 10ppm prior to startup and 25ppm after one washing and drying cycle. A sample collected near a condenser pipe of the adsorber indicated a PCE concentration of 50ppm. Concentrations were well within the OSHA permissible 8 hour TWA concentration of 100ppm PCE and the acceptable ceiling concentration of 200ppm, not to exceed a maximum of 300ppm for 5 minutes in any 3 hour period. The author recommends that exposure to PCE be restricted as much as possible because of its potential hazard as a carcinogen.
